The present invention relates to a method for manufacturing functional rice. The method for manufacturing functional rice comprising: a high pressure washing step for washing rice by spraying water on the rice at high pressure; a cold air drying step for drying the rice washed at the high pressure washing step with cold air; a vacuum drying step for putting the rice in a vacuum chamber and then decompressing the interior of the vacuum chamber at constant pressure in order to improve the porosity of the rice by forcibly desorbing free water contained in the rice dried with cold air; a spraying step for spraying an impregnation solution on the surface of the rice decompressed at the vacuum drying step; a pressurizing step for pressurizing the rice in order to let the impregnation solution permeate the pores of the rice by injecting high pressure nitrogen gas; and a drying step for drying the rice pressurized at the pressurizing step at room temperature. According to the method of the present invention, a technique, which increases the impregnation rate so as to let functional ingredients permeate into the rice and prevents a crack can be occurred on the surface of the rice through the process so as to improve the quality of the rice, is provided. |
